iStock/Thinkstock(LONDON) -- London's Metropolitan Police detained a man Saturday after a car collision left several pedestrians injured near two major museums in the British capital, and later said they are not treating the incident as terror-related.

Police said the collision occurred Saturday afternoon on Exhibition Road in South Kensington near the Victoria and Albert Museum and the Natural History Museum. A man was detained at the scene, police said.

Peter McKenna, deputy director of operations for the London Ambulance Service, said 11 patients were treated, mostly for leg and head injuries. Nine of them were transported to the hospital.

Massive crowds of families with young children were seen evacuating museums along Exhibition Road following the incident, as authorities cordoned off the area.

London Mayor Sadiq Khan released a statement on the incident, saying, "A number of people have been injured in an incident involving a car in Exhibition Road, South Kensington. A man has been detained by police.”

Khan said details about the incident are still emerging and that he is in close contact with police and emergency services.

Police have asked people to avoid the area while the investigation is underway, the mayor said.

Authorities said they are still working to establish the circumstances and motive surrounding the incident.
